Embedded Systems ans internet of things

1. System Overview and Architecture Function of Components in Embedded System Development Presented by: Your Name, Dept. of EEE

2. Introduction Embedded systems: specialized computing units for dedicated tasks Task-specific, real-time, resource-efficient Examples: washing machine controller, automotive ECU, smart meters

3. Embedded vs General-Purpose Computers Purpose: Dedicated task vs Multiple tasks Interface: Minimal UI vs Rich GUI OS: RTOS / Bare-metal vs Windows / Linux Performance: Real-time, low power vs High throughput Examples: ECU, Smart meter, Router vs Laptop, Desktop

4. Architecture Overview Layers: Hardware, Firmware/RTOS, Application, Interfaces Hardware: MCU, memory, sensors, actuators Firmware/RTOS: timing, device drivers Application: main system logic Interfaces: UART, SPI, I2C, USB

5. Hardware Components MCU/MPU executes instructions Memory: Flash and RAM Sensors: input collection Actuators: output actions I/O ports link peripherals Stable power supply ensures correct operation

6. Firmware / RTOS Firmware controls hardware (drivers, timers, interrupts) RTOS enables multitasking, deterministic behavior Bare-metal: single loop task; RTOS: multiple tasks with priorities

7. Application Software Implements main system logic (temperature control, motor speed) Relies on firmware for hardware interaction

8. Interfaces UART: simple serial communication I2C / SPI: multi-device communication USB / CAN: high-level communication Ensures seamless interaction between MCU and peripherals

9. Development Tools Editor: code writing (VS Code, Keil) Compiler/Assembler: convert to machine code Linker/Locator: arrange memory layout Programmer: flash MCU Debugger / Simulator: test and validate system

10. Integration All layers work together: sensors -> MCU -> firmware -> application -> actuators Tools support development, testing, and debugging

11. Summary Embedded systems combine hardware, firmware, application, and interfaces Architecture organizes complexity and ensures efficient operation Foundation for understanding embedded system development
